I assume we have a drop down list (DropDownList1) one the page with following structure,

ASP.NET

<asp:dropdownlist id="DropDownList1" runat="server" datatextfield="Name" datavaluefield="Id" xmlns:asp="#unknown">
</asp:dropdownlist>

and related code behind to populate the DropDownList with data,

C#

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        IList persons = new List<Person>()
        {
             new Person(){ Id="1", Name="A"},
             new Person(){ Id="2", Name="B"},
             new Person(){ Id="3", Name="C"},
        };

        DropDownList1.DataSource = persons;
        DropDownList1.DataBind();
    }

    public class Person
    {
        public string Id { get; set; }
        public string Name { get; set; }
    }
}

So from the above code we can seer, I created a Person type with two property Id and Name. I set the Id as value field for the DropDownList and Name as Textfield.

I Created a List of Person and set that list as data source of the DropDownList. Finally to Bind the data source with the DropDownList using DataBind().

Note: I have done all these on a page named Default.aspx

Hope it helps :)

C#

Dictionary<int,string> list=new Dictionary<int,string>();
list.Add(1," Car");
list.Add(2," Bus");
list.Add(3," XYZ");
dropItems.DataSource=list.toList();

or for your problem We need Create List of Vehicle Class as

C#

public class Vehicle
{
 public int ids  {  get;set;}
 public string Name{get;set;}
}

Then load it ...........................

C#

List<vehicle> Vehicles=new List<vehicle>;
Vehicles.Add(1," Bus");
Vehicles.Add(2," Car");
Vehicles.Add(3," XYZ");
dropItems.DataSource=Vehicles;

or you can get it from Database from Vehicle Table or something.
I think you have your solution.

Solution 2

if you get the values from a db query
then you can make...

C#

var result = RESULT_OF_YOUR_QUERY;
dropItems.DataSource=result;
dropItems.DataValueField = "ids";
dropItems.DataTextField = "Name";
dropItems.DataBind();
